SuperNova dash air?

[PieEye]

Anyone have problems with the dash heat/air. Mine will just blow air (either hot or cold) out the vents regadless on what the vent control or fan speed is on. Its like you have the fan on high and the vent switch to vents, even if you switch it to floor and have the fan speed set to low.

Any ideas?

I would take it to International. I had a similar problem with my Kodiak chassis coach and it was the air blending unit which GM replaced under warranty. My International works well.

Thanks. Thought I would check just in case someone else had experienced the same thing and it was a simple, do it yourself fix.
